Desenvolvimento de sistema computacional para o dimensionamento de lajes de concreto armado como ferramenta de auxílio acadêmico
Resumo
This work has as objective the elaboration of a computational system, called DIMILAJES,
that generates a routine of calculations for the dimensioning of reinforced concrete slabs,
using the Visual Basic for Applications (VBA) through Microsoft Office Excel. The adoption
of this programming language aims to make use of it pleasant through a simple, intuitive, and
practical graphic interface, since it has help buttons, graphics, and textual elements to
facilitate use. Through the user's input data, the system efficiently, accurately, and
automatically scales slabs with latticed, ribbed, and solid joists of rectangular geometry,
submitted to a uniformly distributed loading, having as prerogative the recommendations of
NBR 6118:2014 - Concrete structure design - procedures. The determination of the bending
moments in reinforced slabs in one direction, unidirectional, occurred by the analogy of a unit
beam strip in the direction of the smallest span. For the determination of the bending moments
for the reinforced slabs in two directions, the simplified Method of Marcus was adopted,
given the better understanding of the calculation mechanisms of this method. In the proposed
example, we tried to compare the values obtained by the system with the reference values of
an example extracted from the bibliography, where the calculations adopted in this system can
be validated and verified that the DIMILAJES system met the initial proposal, being viable its
academic and professional use.
